When the pressing portion 71 is pressed in the using state, the linkage portion 72 is pried up, the pen clip 6 is lifted up, the locking relationship between the locking piece 42 and the locking boss 61 is released, and the locking piece 42 falls back under the influence of the return spring 5, so that the pen core is retracted and becomes the non-using state.

When the pressing force on the pressing portion 71 disappears, the linkage portion 72 receives the deformation restoring force of the pen clip 6, and the remote control link 7 is pressed and restored after the rebound restoration.

The remote connecting rod 7 can be reset after the pressing force disappears in a magnetic suction mode.

Other embodiments, besides embodiment 7, the third operation mode mentioned above can be added

The embodiments 2 to 7 all have self-locking function, and the specific self-locking scheme is as follows:

still be equipped with auto-lock buckle 66 on above-mentioned pen clip 6, above-mentioned auto-lock buckle 66 downside still is equipped with auto-lock draw-in groove 661, and above-mentioned pen clip 6 makes pen clip 6 adjust to the auto-lock position through rotatory, then can make locking piece 42 card go into in the auto-lock draw-in groove 661 to realize outer pole 3 and interior pole 2 structure relative locking, the refill can't expose. When in use, the pen clip 6 needs to be rotated and adjusted to the use position in advance.

The self-locking latch 66 of embodiments 2 and 3 is parasitic on other structures, such as the self-locking latch 66 of embodiment 2 is parasitic on the lower side of the reset limiting table 63, and the self-locking latch 66 of embodiment 3 is parasitic on the lower side of the long distance limiting table 65.

The self-locking buckle 66 of embodiments 4-7 is an independent component, and is divided into one side or two sides according to specific structural characteristics. The above-mentioned self-locking function can be additionally added to the above-mentioned embodiment 1.

The self-locking operation modes of the above embodiments 2 and 3, because the pen clip is provided with the barriers limited by the reset limit table 63 and the long-distance limit table 65, the specific operation modes are as follows:

1. rotating for nearly one circle to enable the locking piece 42 to be clamped in the self-locking clamping groove 661;

2. utilize the deformation power of pen clip for the crooked deformation back of pen clip avoids the spacing platform 63 that resets and the spacing platform 65 of long distance to take place to contradict with locking piece (42), and the rotation of minor amplitude is a bit again, makes locking piece 42 block in self-locking draw-in groove 661.

The self-locking operation mode of embodiments 4 to 7 is not limited, and the locking member (42) can be directly locked in the self-locking slot 661 after being rotated by a small amount.

If the self-locking function is adopted, the pen clip is required to be rotated and fixed. The invention provides a pen clip with a function of rotation and fixation, and the specific scheme is as follows:

the pen clip 6 is composed of a pen clip hook 6Y and a pen clip main body 6U. The pen clip hook 6Y is separated from the pen clip main body 6U, so that the pen clip 6 can be rotated conveniently. The pen clip hook 6Y and the pen clip main body 6U can be provided with a rotary buckle structure, so that the stability of the use position and the self-locking position, the smoothness of the rotation process and the stability between the pen clip 6 and the outer rod 3 are ensured. The pen clip hook 6Y is internally provided with a rotary inner ring 6Y 1. The rotating inner ring 6Y1 is also internally provided with a use position clamping groove 6Y11 and a self-locking position clamping groove 6Y 12. The pen clip main body 6U is also provided with a clamping boss 6U4 clamped with the position clamping groove 6Y11 and the self-locking position clamping groove 6Y 12.

For embodiments 1, 2, 5 and 6, there is a certain requirement for the upward-tilting displacement capability of the locking boss 61 on the pen clip 6, and the upward-tilting displacement capability of the locking boss 61 mainly depends on the deformation capability of the pen clip 6 itself and the upward-tilting displacement capability of the pen clip hook 6Y, for more convenient use, we can further improve the comfort of use and reduce the requirement for the deformation capability of the pen clip 6 by improving the upward-tilting displacement capability of the pen clip hook 6Y, and simultaneously improve the durability of the pen clip 6, while embodiment 2 adopts the following deformation auxiliary scheme to structurally improve the upward-tilting displacement capability of the pen clip hook 6Y:

the clip main body 6U may be composed of a clip inner body 6U1, a clip outer body 6U2 and an auxiliary spring 6U 3. The clip hook 6Y and the secondary spring 6U3 are located between the clip inner body 6U1 and the clip outer body 6U 2. The auxiliary spring 6U3 is specifically positioned between the pen clip hook 6Y and the pen clip outer body 6U 2. The pen clip inner body 6U1 and the pen clip outer body 6U2 are matched in a threaded, clamping and magnetic attraction mode. In the embodiments 1, 5 and 6, the deformation capability and deformation tolerance of the pen clip can be improved by adopting the deformation auxiliary scheme, and the use times and comfort are improved; the auxiliary spring 6U3 and/or the return spring 5 may be replaced by an elastic press piece or other elastic objects.

The requirement for the pen clip hook 6Y is to ensure that it has a certain capability of being displaced obliquely upward and at the same time ensure that it does not clear up the upward displacement, otherwise it will cause unnecessary obstruction to the engagement between the locking piece 42 and the locking projection 61, and this unnecessary obstruction can be reduced by:

the elastic force of the auxiliary spring 6U3 is larger than that of the return spring 5 and/or a bevel pressure relief opening 6U5 is arranged at the lower part of the pen clip outer body 6U 2. The inclined pressure release port 6U5 is far away from the locking boss 61 end of the pen clip hook 6Y and is tightly attached to the pen clip hook 6Y, and the closer to the locking boss 61 end, the farther from the pen clip hook 6Y, the integral inclined line is kept, so that the pen clip hook 6Y generates upward inclined displacement, and the locking boss 61 can move upward in an inclined manner and cannot move upward integrally.

The embodiments 1 to 7 all adopt the performance improvement scheme, which is as follows: a cover 24 is also arranged below the pen clip 6. The cover 24 is engaged with the outer rod 3 by means of screw thread, snap fit or magnetic attraction.

If the reset spring 5 is specifically positioned between the inner rod 2 and the pen clip 6 and the reset spring 5 is not added between the inner rod 2 and the pen core 1, a positioning soft body 8 is arranged in the front end of the inner rod and used for preventing the pen core head from shaking.

If the return spring 5 is located between the inner rod 2 and the pen clip 6. A spring carrier 23 for carrying the return spring 5 can also be added to the inner rod 2. In order to avoid that the return spring 5 presses the pen clip 6, which would reduce the rotation effect of the pen clip 6, the return spring 5 is instead located between the spring carrier 23 or the inner rod 2 and the cover 24 or the pen clip 6.

If a cover 24 is used, the return spring 5 is optionally located between the spring carrier 23 or the inner rod 2 and the cover 24 or the pen clip 6. The cartridge 1 is instead stuck in the cap 24.

A pen core soft rubber sleeve 25 can be arranged in the sealing cover 24. The pen core soft rubber sleeve 25 is clamped in the sealing cover 24, a gradually reduced clamping channel 251 is arranged in the pen core soft rubber sleeve 25, and the pen core soft rubber sleeve 25 and the sealing cover 24 are matched in a clamping, threaded or magnetic suction mode and can be matched with pen cores of different specifications. And provides a slight comfortable rebound for writing. The tail part of the sealing cover 24 is also provided with an adjusting groove which can be matched with an external tool to adjust the thread matching degree between the sealing cover 24 and the outer rod 3. Thereby adjusting the elastic force of the return spring 5.

The inner rod 2 is also provided with a limit convex ring 221. A limit ring table 33 matched with the limit convex ring 221 is also arranged in the outer rod 3. The outer diameter of the limit protruding ring 221 is larger than the inner diameter of the limit ring table 12.

After adopting above-mentioned spacing bulge loop 221 and spacing ring platform 33, when not using promptly, realize the biggest spacingly through spacing bulge loop 221 and spacing ring platform 33 to avoid the bottom of locking piece 42 and notch 31 to produce the conflict power, prevent that locking piece 42 from receiving long-time extrusion, then need not prevent the whole separation of pen-holder through the restraint relation of cup jointing between locking piece 4 and the notch 31, very big improvement cup joints the durability and the stability of locking piece 4.

Through the performance promotion scheme, the locking piece 4 is cup jointed in durability, wholeness, use comfort, structural stability and the better protection of the whole pen of improvement that can be very big, still provides the adjustable function of reset spring 5's elasticity simultaneously, can adjust reset spring 5's elasticity wantonly to required dynamics size when changing the operation pen, the different use crowd of adaptation.

In order to replace the pen core better, more conveniently and more scientifically, the
